Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irrigation sprinkler systems face challenges in achieving uniform water distribution around a covered area, with existing solutions often requiring complex constructions to manage water streams effectively.
Innovation Solution
A rotating sprinkler design featuring a movable core with a cover, impact member, and stream deflector that pivots and splits the water stream into two streams, where one stream is emitted unobstructed and the other impacts an impact member to power the sprinkler's rotation, utilizing a gear train to ensure even distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex construction is used to manage water streams and achieve uniform distribution, then water distribution uniformity is improved, but device complexity increases
Solution Approach 1:
The water stream is divided into multiple discrete streams by the stream deflector, with each stream directed at a different angle to create a distributed spray pattern. This segmentation of the water flow achieves uniform distribution without requiring complex mechanical mechanisms.
Solution Approach 2:
The impact member is designed to pivot dynamically between positions, allowing the sprinkler to automatically adjust its operation based on water flow conditions. This dynamic element simplifies the overall construction by replacing complex control mechanisms with a self-adjusting mechanical response.
2Ease of operation
If the impact member pivots freely to manage water stream back-impact, then water stream control is improved, but reliability decreases due to potential reverse re-alignment
Solution Approach 1:
The stream deflector is positioned and angled to preemptively counteract any back-impact forces on the water stream before they can cause harmful reverse re-alignment. This preliminary counter-action ensures reliable stream direction while maintaining ease of operation.
Solution Approach 2:
The stream deflector acts as an intermediary element between the water stream and the impact member, mediating the interaction to prevent direct harmful contact that could cause reverse re-alignment while still allowing the impact member to pivot for stream control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves uniform and efficient water distribution by utilizing vector forces to incrementally rotate the sprinkler, ensuring consistent irrigation coverage without back-impact and reverse re-alignment of the water stream.
Implementation Method 1
the second liquid stream at least partially impacts against the impact member to power movement in the gear train that in turn urges rotation of at least a portion of the sprinkler about sprinkler axis X

AI summary
A rotating sprinkler includes a housing and a movable core. The core can assume retracted and extended states relative to the housing and incudes a cover, an impact member and a stream deflector. In the extended state, both the cover and the impact member can pivot between pivoted and non-pivoted states about a hinge defining an axis H generally orthogonal to axis X and the stream deflector is fixed against rotation about the hinge.
